The lower temperature range from -60°C (-76°F) to 400°C (752°F) undergoes Habonim’s unique surface treatment, LTPN (Low Temperature Plasma carbo-Nitriding). LTPN is a cost effective hardening system for austenitic stainless steel, which provides a minimum thickness of 40 microns and more than triple (>68HRC) the natural hardness of the base material. For the higher temperature range from 400°C (752°F) and up to 538°C (1000°F) Habonim offers various HVOF spray solutions based on chromium and tungsten carbides.

For the even higher temperature range from 538°C (1000°F) and up to 650°C (1200°F) Habonim uses ASME B16.34 listed forged bar material for the construction of the valve pressure-containing elements.

For the severe abrasive conditions of the pulp and paper industry, Habonim offers also a minimum of 1.5 mm thick, hard stellite coating. Each coating is specifically engineered to the customer’s application in order to provide outstanding resistance to abrasion and corrosion for a lifetime of effective operation in harsh applications.

Each ball and seat sub-assembly is accurately machined, ground and then mate-lapped for a perfect match. The complete valve assembly demonstrates high repeatability in terms of sealing (Rate B – factory tested), low torque and smooth operation at various temperatures and pressures. Habonim uses ASME B16.34 listed cast material for the valve body and ends.
